Remove orf fix parallel deployment example

While working on https://github.com/owncloud/ocis/pull/5637 we noticed that the deployment example is currently in a very sad state (mostly unmaintained and untested). I might be me, but I was not able to get the deployment working at all. ( E.g. amongst other things the oc10 container was restarting all the time).

There is quite a few open issues around the parallel deployment in general:
https://github.com/owncloud/ocis/issues/4326
https://github.com/owncloud/ocis/issues/2547
https://github.com/issues?q=is%3Aopen+is%3Aissue+label%3AStorage%3AownCloudSQL+

Which haven't been taken care of since quite a while.

If we don't have the resources to keep the sample deployment alive, I would rather prefer removing it from the repo for now, than creating a bad impression by providing non-working examples . We can always get it back from the git history when ever we want to spend time on it.

@micbar @tbsbdr Any opinion on this?
